A Low Level Deck is one that only involves low level monsters (4 or lower, though level 3 is optimal for this design), and usually focuses on some of the more powerful effects rather than actually attacking to overwhelm your opponent. Closely related is the Low ATK Deck which is essentially the same, but can also include higher level monsters that have low attack, usually under 1000, though less than 1500 can also be considered low. Both use a similar strategy of getting otherwise weak monsters, usually Flip Effect monsters, on the field and activating their effects in order to clear your opponent's field of monsters and then attack directly.
